Referring toithewform of my invention shown Figs. 1 to '7, inclusive; acircular discmemberlil' of wood or'other-"suitable material is providedwith'a central openingill and an annular groove 5| in its front face forreceiving an annular member 52 "of the same material. Positioned I inthe opening is a' bushing 53"supporting' an inner "sleeve 54 andextending through said' sleev'e' rearwardl'y of'the disc member is ashaft55i The front" end of the shaft is provided with an axial screwthreaded bore 55' for receiving a s'crew threadedbolt fil with"anenlarged head 58. A" g-lobe3'5 is rotatably' mounted on: the bolt, andclamped between the sleeve member- 54 and a washer 59 by means 'ofsaidglobe on the bolt 5T'is a'transparentdis'c' l7; Thisdisc'covers thefront face of"thedisc member 4-9 to a point remote from'the inner'p'eriphery' of the annular member 52 leaving a space-18 between theiradjacent pe ripheries;

Keyedto th'e'shaft 55 rearwardly of thedisc member-flier rotation withsaid shaft isadisc" member fifland rotatably mounted on said shaftrearwardlyof "the disc member 60 is anotherdisc member 6|; This discmember 6| rotates on roller bearings- 62 positioned between the' sh'aftand hub of'the'disc. Keyed to the shaft rear wardly of the disc BI is aspur gear 63. 'Disc member" 6T is provided with an annular enlarged"portion 64' for supporting a ring member 65 having teeth'66 on itsouter'periphery. Fastened" to the disc'memberliWby bolts 6'! is adiscwheel 68provided"with teeth BQbn-its outer periphery.

Another 'disewheel 10 is fastened to the disc member 61 I by. welding"or other suitable means and this wh'eel'is provided with teeth 'H on itsouter. periphery. rearsurfa'ce'of thedisc'member 49.

At spaced intervals adjacent the outer" riphery'of disc member 49 aretiming devices cent its 1 periphery and rearwardly through i the covermember 12. The hour hand 13' is: fas tened to the *ou-teriend 10f theshaft 151by a bolt 1T andtheminute hand is wedged on to the outer end ofa sleeve member T8 rotatably mount-- ed; onshaftz'i5.

gear 8w:is keyed1 tothe sleeve'mem-ben 18 in A cover 12 i'sfastenedonithe Keyed 'to shaft 15 in alignment and continuous mesh with"the teeth of disc? wheel-Nils a-spur gear H3, and: a similar-spun and isdriven thereby. On the same shaft is another toothed wheel 86 spacedfrom but turnable with toothed wheel 84. Toothed wheel 86 is in meshwith a broad faced gear 81 supported on a shaft 88 on the cover, anddrives said gear 81. Gear 8! is in mesh with the teeth 66 on the gearring 65. It will be seen that when the globe is turned manually foradjusting or other purpose the drive is brought from the shaft 55directly to disc member I! and disc wheel 58 and from said wheel to theminute hand I4, but that said drive is transmitted to the disc mem berGI and disc wheel I through the gear 63 and gearing in the offsetportion of the cover and from the disc wheel I0 to the shaft I and hourhand I3. The gearing is so constructed and arranged that the hour handI3 moves twenty-four times slower than the minute hand.

The shaft 55 may be driven by a motor 39 as shown in Figs. 4 and 5. Insuch case, the shaft is provided with a worm Wheel 80 on its outer endwhich is in mesh with the worm drive shaft 9! of the motor. fordisconnecting the shaft 55 from the motor when'the shaft is to be turnedmanually.

In the form of the inventions shown in Figs. 8 to 14, inclusive, theglobe 9|, transparent disc I! and the hour and minute hands of thetiming devices may move simultaneously and in unison as in the form ofthe invention shown in Figs. 1 to 7, inclusive, or the transparent discmember and globe may move independently or separately of the hour andminute hands. This is accomplished by providing mechanism for dsconnecting disc wheels 68 and I0 from the drive shaft 92. In this formof the invention, the drive shaft 92 is hollow or tubular. On the outerend of the shaft is the globe or hollow spherical member 9| having innerand outer complementary members 93 and 94, the inner member being screwthreaded to the shaft 92 and the outer m mber threaded to the innermember. Transparent disc I! is threaded on the shaft between the flangeof a sleeve member 95 and .a washer 96. Slidable in the outer end of theshaft 92 is a plunger 9! normally pressed inwardly by a s ring 98 whichhas one end seated on a flange 99 on the inner end of the plunger andits other end seated against a shoulder I00'on the sleeve member I0!which is threaded on to the shaft 92 and forming an extension thereof. Aknob or handle I02 is fastened to the outer end of the plunger foractuating the same. A lever or link member I03 is positioned in thehollow shaft 92 and has one end pivotally connected to the inner end ofthe plunger and its other end is slotted and slidably connected to a pinI04 supporting a key member I05 extending through an opening in theshaft 92 in alignment with the hub portion of disc member 60, which keymember is adapted to engage a keyway in said hub portion. Another linkmember I06 has one end connected to the pin I04 and its other endconnected to a. similar pin 4 I07 supporting a key member I00 extendingthrough an opening in the shaft 92 in alignment with the spur gear 53and adapted to be en aged in a keyway in the hub portion of said gear. Alink member I00 similar to link member I03 has one end slidablyconnected to the key member I00 and its other end pivotally connected tothe inner wall of the hollow shaft 02. In Fig. 8, the key members I05and I08 are shown in driving position in the keyways of the disc memberBI and gear 63 and rotation of the shaft 92 manually or by motor will beimparted to said disc member and gear. The toggle action of the linkagecauses the key members I05 and I03 to move into and out of the keyways.

In this-form of the invention, the hour hand II0 is fastened to anelongated sleeve member III rotatable and slidable on a stub shaft H2supported by the disc member 09 and the cover I2. Gear teeth I I3 areformed on said sleeve member I I I adapted to mesh with the peripheralteeth of disc wheel 10 whereby said sleeve member and hour hand arerotated. j

The minute hand I I4 is supported by awasher member II 5 fastened to asleeve member I16 rotatable on the sleeve member III. Sleeve member I I5is formed with gear teeth I I I adapted to mesh with the peripheralteeth of disc -j wheel 68 whereby said sleeve member H6 and Means may beprovided 3! minute hand are rotated. Sleeve members III; and I I5 areadapted to slide in unison on the shaft I I2. In Fig. 8, the disc wheelsand gear teeth are shown in operative position. In Fig.9; said discwheels and gear teeth are shown separated in inoperative position. Thisis accom.-: plished by first removing a washer member H0 which isremovably mounted in an inner peripheral groove H9 in the shaft H2 andslidingthe sleeve members III and II 6 outwardly on the shaft to the poition of Fig. 9. The removed washer is then mounted in an outer grooveI20 on the stub shaft. A pin I2I on the sleeve. III acts as a stop tolimit the outward movement of the parts. To restore the parts tooperative po-; sition, the movable parts are slid inwardly to innermostposition and the washer H0 is again mounted in the inner groove H9.

In Fig. 9, the disc member 60 and the gear 53 are also showndisconnected from the drive shaft 02. This is done by first removing theouter section 94 of the globe and then pullingout the plunger 01 bymeans of the handle or knob I02 against the action of spring and becauseof the toggle action of the linkage supporting the key members I05 and I08, said key members are pulled out of the keyways-011 disc 60 and. gear63, respectively. The parts are held in disconnected position by aspring pressed pin plunger I22 adapted to move into an opening'or socketI23 formed in the sleeve member IIBI. In order to release the holdingplunger I22 to'permit the spring 98 to move the plunger inwardly;

to position to connect the parts with the drive shaft 92, I haveprovided a movable pin 12s carried by a flat spring I25. The pin IN isin alignment with and is adapted to engage plunger pin III) 22 and forceit outwardly of the socket mem er.

In order to permit the key members I 05 and I08 to return to theirrespective keyways in the disc member 60 and gear 63, the disc wheels 30and I9 must be held so that their key ways are in alignment. This isdone by the mechanism shown in Figs. 10 and 11. I

At a point along the periphery of the disc masseuse member-49, betweenone pairof adjacentftiming devices, a: pair of shoe. membersfltandlllflitare 'pi-votally connectedto the inner surface of the discmember laand the. innervsurfa'ce-of the cover 12, respectively, as shownin Figill'l Each shoe comprises aflat body portion I28 with offsetspaced. fingers I29, each finger having a pressed out protuberance it.Whcntheshoe members are in operative position, the fingerson the shoemember IZi eXtend'thrOugh the slots between the fingers on the sho'ememberlzl.

The finger members are positioned between-the upper: edges'ofthe'discwheels 68 and'le; EX- tending through an opening in the cover '52 inalignment with the shoe members is a screw threaded shaft I3! with awedge-shaped head I32 on its inner end and an actuating handle I33 onits outer end. The wedge-shaped head is positioned between and inengagement with the flat body portions of the shoe members. A spring I34holds the shoes I and I23 normally together. Upon inward movement of theshaft, the finger members will be spread apart and the protuberancesthereon will clampingly press the disc wheels 58 and Ill between saidfingers and brake shoes I35 and H36 mounted on shouldered portions ofthe disc member 59 and cover l2 to hold said wheels against movement.This holds the wheels in the same relative position and keeps thekeyways in the disc member 66 and the gear 63 in alignment.

The improved apparatus may be supported by means of brackets clamped tothe bottom of the member 49 or in any other suitable manner.
